The object of the invention is to provide a control apparatus (C) of a horizontal axis wind turbine apparatus (WTG) that calculates the value en of a pitch angle command for each blade based on the rate of change (¨D) of the azimuth angle (¨) of a nacelle (N) and the rotor azimuth angle (Æ) of the blades (B1, B2 and B3), causes the rotor (R) to generate torque around the yaw axis by periodically controlling the angle change of the pitch angle of the blades (B1, B2, B3), and using that torque, controls the rate of change of the azimuth angle of the nacelle (N). The value of that angle change is calculated as a value that increases as the input value of the rate of change (¨D) increases. |
